The Cometary Science Newsletter is dedicated to sharing and furthering
cometary science. CSN invites contributions from the astronomical and
planetary science communities, including abstracts of papers accepted
for publication in refereed journals, thesis abstracts, timely notes
on particular comets, conference announcements, job announcements, or
other relevant and brief scientific communications. Relevant topics
include observational, theoretical, and laboratory work concerning
comets, but also may include studies of associated phenomena, such as
Centaurs, asteroid-comet transition objects, debris disks, and
protoplanetary disks.
